What are the key electrical specs?

It features 120Ω impedance at 100 MHz, a maximum DC resistance of 0.009Ω, and a rated current of 6A at 85°C.

What mounting method is required?

This component is designed exclusively for reflow soldering.

How does temperature affect the rated current?

The rated current derates from 6A at 85°C to 4A at 125°C.

What are the sourcing risks?

As a standard Murata component, it has high availability, but users should ensure proper storage conditions to maintain solderability.
